Really, rarely any premium:

1932 US Caramel McKinley
Marquis de Lorne
Any SP Wacky Package like Ratz Crackers
1977 Star Wars C3PO "Goldenrod"
1959 Fleer 3 Stooges #1
Any N or T card of George Washington or Thomas Edison
T70 signing of the declaration of independence
1883 Pratt Oil Statue of Liberty trade card
I collect William Sherman's N cards and they are always at a premium to other generals in the same sets.
1979 Warner Bros Prince, Bob Marley sell at 100x what Wire or M or Foghat fetches.
The N76 Lincoln in a PSA 6 went for over $13,000 last week. Any other five-figure sales in that set? Four-figure sales??

I could go on and on listing cards with large relative premiums to others in the same sets.

Your precious nonsports is collected by the same sorts of people who are here: humans. No differences in behavior, just magnitude.
